[wix-users] How to use WcaReadStringFromCaData?

[Joel Budreau]

More Info:

Today I pass ca data like "param1;param2", so I have added code similar to
this in my custom action:

   // Replace ";" delimiters with wcautil-friendly 'magic' delimiter
   WCHAR delim[] = { MAGIC_MULTISZ_DELIM, 0 }; // magic char followed by
NULL terminator
   hr = StrReplaceStringAll(&pwzCaData, L";", delim);
   ExitOnFailure(hr, "Failed to replace CustomActionData delimiters");
   pwz = pwzCaData;
   hr = WcaReadStringFromCaData(&pwz, &pwzParam1);
   ExitOnFailure(hr, "Failed to parse Param1.");
   hr = WcaReadStringFromCaData(&pwz, &pwzParam2);
   ExitOnFailure(hr, "Failed to parse Param2.");

This seems to defeat the purpose of using the 'magic' character in the
first place, right?
